Have you considered using XMLSERVICE instead?​

youngiprofessionals.com/wiki/index.php/XMLSERVICE

XMLSERVICE doesn't suffer from a number of ailments that PCML+IWS does
(i.e. "Can't imagine being restricted to not being able to return anything
but 4-byte integers." this isn't an issue in XMLSERVICE)

Got the RNF0302 on my module compile, when compiled with PGMINFO(*PCML :

"Error: return value must have type="int" and length="4". (E)."

Archives indicates that a return value is restricted to a 4-byte integer.
IBM Knowledge Center for i 7.1 shows a number of data-types not supported
for return/input parms (char is not one listed as excluded), and also has
the following verbiage regarding output-only parms:

<snip> RPG does not have the concept of output-only parameters. Any
parameters that do not have CONST or VALUE coded have a usage of
"inputoutput". For inputoutput parameters, the ProgramCallDocument class
requires the input values for the parameter to be set before the program
can be called. If the parameter is truly an output parameter, you should
edit the PCML to change "inputoutput" to "output". </snip>

Okay, fine. RPG (at 7.1 TR7) does not allow CONST or VALUE on the return
parm (except VALUE for INT 4.0 only). So how might one edit the PCML if a
module fails to compile? And just where does one find the PCML to edit?

Or better, how might one set up an acceptable return parm that permits a
character string?

I am doing some proof-of-concept work for ultimately creating a web
service with IWS to support an Electronic Bill Presentation & Payment
application. I was able to create the web service for a procedure that
didn't return any values, but as I expand toward real world work, I crash
into this. Can't imagine being restricted to not being able to return
anything but 4-byte integers.

How do real developers do this?

Many thanks,
